We look at the division of 743243 by 10 
We want to figure out the number of times 743243 can be divided by 10.

Moving on to step 1:
When dividing 7 by 10, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 10

On to step 2:
10 goes into 74 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 70 from 74 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 10

On to step 3:
10 goes into 43 4 times with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Subtracting 40 from 43 leaves us with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 10

On to step 4:
32 divided by 10 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 743.0
Subtract 30 from 32 to get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 10

Step 5:
24 divided by 10 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 7432.0
If we take 20 away from 24, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 10

Moving on to step 6:
The number 10 fits into 43 4 times, leaving a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 74324.0
If we subtract 40 from 43, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
10 goes into 30 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 74324.3
If we subtract 30 from 30, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 74324.3
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
If we divide 0 by 10, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 74324.3
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 74324.3, with a leftover of 0.0.
